//A460 BIG BLOCK FORD
To create the A460 Big Block Ford performance cylinder head, MBE pulled together lessons learned from its winning NHRA and IHRA Pro Stock programs along with its 18 record-holding Comp Eliminator customers to develop ports that are perfectly sized to both maximize airflow and port velocity. With 2.500-inch intake valves and 1.830-inch exhaust valves installed, the precisely
designed ports flow an astounding 522 cfm through the intake and 344 out of the exhausts. And remember, MBE is the only induction specialist willing to stand behind its advertised flow numbers with a guarantee that you will see the same or better performance on your own flow bench.
To get to this incredible level of performance, MBE had to make changes to everything from the valve sizes, to the port locations, to the shape of the combustion chambers, but this is what was required to finally make the absolute best power from Ford’s notoriously inefficient A460 heads. And the advancements
are substantial all the way across the board. While the peak flow numbers are impressive, it’s just a sign of the overall flow capabilities if this cylinder head. Mid-lift flow is also improved as much as 25 percent over the best existing heads out there. With the improvements MBE has made, this is now an excellent cylinder head for Throttle Stop and Top Sportsman racing, including Super Comp and Super Gas, and it works extremely well in nitrous applications. This, in fact, is also an excellent cylinder head
for Truck pulling. Mitchell Coomer is just one of the pullers currently using MBE’s A460 head to power his engine program to big wins.
To squeeze the absolute most power out of your engine combination, MBE also produces a cast intake manifold custom ported to perfectly match the characteristics of the cylinder head. To put it simply, this is the best A460 Big Block cylinder head you can buy for big cubic inch engine packages (typically 460 to 600 cubic inches), especially if you need a head that keeps making power at rpm levels that are way beyond the point that the competition has flatlined.
